Symptomatic mitral regurgitation is frequent in the elderly population. A significant proportion of patients are not eligible for mitral valve surgery because of significant morbidity and mortality risks. There is therefore a need for a less invasive alternative for this patient population. Several new transcatheter devices designed to treat mitral regurgitation have after encouraging trials, been applied in clinical practice. The most common cause of mitral stenosis is rheumatic fever. We present an overview of the pathophysiology, diagnosis, evaluation of severity and choice of treatment of mitral stenosis. We also give a description of how percutaneous mitral valvulotomy is performed.
